How to grow kiwifruit

Kiwifruit is a kind of vine, and T-shaped frame, greenhouse frame and small scaffolding are widely used in order to provide excellent growth environment for kiwifruit. The T-shaped frame needs to set up a pillar first, and then a crossbeam on the pillar; the erection of the large scaffolding is roughly the same as that of the T-shaped frame, except that triangular iron or steel strands are used to tighten the pillar; most of the small scaffolding is in the shape of a "door", which is basically consistent with that of the greenhouse.

Kiwifruit is a vine, in order to ensure that they can maintain a good growth state, it is necessary to set up supports. At present, T-shaped frames and large scaffolding are often used in planting, and many informal scaffolding have been banned.

1. T-shaped frame

The cost of this kind of erection is lower, and the erection is relatively easy, which is convenient for field management and operation in the future, and the ventilation and lighting in the planting hospital will also be better, which is beneficial to bee pollination and promote the acquired fruit of rice.

The T-shaped frame is to set up a pillar first, and then set a crossbeam on the pillar to form a T-shaped bracket, which is generally set up about 6m in each vertical line.

The length of the column should be controlled at about 2.5m, the height of the support on the ground is about 1.8m, it is buried in the ground about 0.7m, and the whole field of the crossbeam is controlled at about 2m. Five No. 8 lead wires should also be set on the upper side, and a central frame should be set at the top of the pillar. The pillars and beams of the bracket can be made of logs with a diameter of about 15cm, or reinforced concrete.

Generally, there should be 4 steel bars in the interior of reinforced concrete, the cross section of the pillar should be controlled at about 12 × 12cm, and the cross section of the crossbeam should be controlled at about 15 × 10cm. A ground anchor cable should be set up at the 2m extension line outside the pillar at the end of each row, and reinforced concrete can also be used to make ground anchor. the length is about 50cm, the width is about 40cm, and the height is about 30cm, which needs to be buried 1m deep underground.

If the pillar uses logs, it needs to be treated with anticorrosion before burying. In order to ensure that the support is strong enough, the diameter of the pillar and side row at both ends of each row needs to be increased by about 2-3cm, 2 steel bars are added inside, the length needs to be increased by 20cm, and the depth of burial also needs to be increased by 20cm.

2. Greenhouse frame

The construction of greenhouse has strong wind resistance, which can improve the yield and quality of kiwifruit, but the cost is higher. New Zealand, the country of origin of kiwifruit, used T-shaped shelves at the beginning. With the continuous development of society and the continuous improvement of technology, the number of greenhouse shelves is increasing.

The specification, planting distance and anchor cable installation of the scaffolding are similar to those of the T-shaped scaffolding, except that the pillars of the scaffolding use triangles or steel strands to pull the pillars of the entire plantation together. On the triangular iron, an No. 8 lead wire should be erected every 50-60cm or so. In addition to burying the anchor wire outside the pillars at both ends of each row, it is also necessary to bury a ground anchor wire 2m outside the pillars at both ends of each row.

3. Small scaffolding

The scaffolding is mainly used in the male plant plantations of kiwifruit. The structure of the scaffolding is generally 2 pillars and 1 beam, mostly in the shape of "door". Generally, the column length is controlled at about 2.6m and the diameter is controlled at about 12-15cm, which needs to be buried in the ground about 0.7m-0.9m, the height above the ground is about 1.8m-1.9m, the length of the crossbeam is controlled at about 3m, the diameter is 10 × 5cm, the distance between the general small scaffolding is about 5-6m, and other matters needing attention are basically the same as setting up the greenhouse.

4. Stand and frame materials are fixed

The best row spacing for planting kiwifruit is 3-4m × 2m, so the row spacing of kiwifruit is best controlled at about 3-4m, but the specific spacing is best adjusted according to the topography of the plantation and the firmness of the frame, which is generally controlled at about 5-6m. After selecting a good frame, a single column and traction wire, you can begin to set up the frame type, generally manage it first, and then bury the posts, to ensure that the posts are upright. Rows and lines can be aligned, preferably horizontally, vertically, left and right oblique. Only by laying a good foundation can the later traction be carried out better.

In order to ensure the stability of the frame, oblique side column, traction and buried anchor and oblique pillar can be adopted to reinforce. Generally, the length of inclined column should be controlled at about 4-4.5m, and steel cable can be selected as oblique wire.
